[0002] Using natural enemy insects to control pests is an effective measure to reduce pesticide residues in crops. The efficient and low-cost natural enemy insect release method is the premise and basis for large-scale application. Ladybug is a relatively ideal natural enemy insect because of its large prey volume, wide range of activities, and the ability to control some small insects besides aphids. It has attracted more and more attention. At present, the method of artificially releasing ladybugs in production mainly uses egg cards and adults, but the release of ladybug eggs requires the early larval stage. The newly hatched larvae have low food intake and other problems, so the control effect will be delayed. On some crops, it is also There is a problem of high mortality rate, and released adults may escape immediately due to fright after release; the multi-heteromorpha coccinella has the characteristics of high predation, high stress resistance, and easy breeding, and is a natural enemy insect with good development prospects. In order to improve the actual application effect of the multi-heteromorpha coccinella after release, it is found through research that the adult ladybugs released in the pupal stage have weaker mobility after emergence and will not escape immediately due to fright. The adult ladybugs have a large prey volume and are quick to take effect. Therefore, a low-cost, easy-to-process application carrier of ladybug pupae and a supporting use method are needed.

[0019] See also Figure 1-4In this embodiment, a releasing device for pupae of a multi-color ladybird beetle comprises a releasing box product 9, which is the main part of the whole device and is used to store pupae of a multi-color ladybird beetle. Insect exit holes 7 are provided on all four sides of the releasing box product 9, and a releasing box extending part 6 is provided on the side of the releasing box product 9 facing upwards. The releasing box product 9 is pasted through a releasing box pasting position 8, and three insect exit holes 7 are provided on the front and back sides of the releasing box product 9, and two insect exit holes 7 are provided on the left and right sides of the releasing box product 9. These insect exit holes 7 are provided to allow the emerged adults to come out of the box, and the insect exit holes 7 on the side are provided at the upper end of the releasing box product 9.

[0020] The release box finished product 9 is made of cardboard. The design of the cardboard should ensure that the user can easily open and close it to put in or take out the ladybug pupa. The release box finished product 9 has a conventional paper box design and is easy to cooperate with mechanical packaging. The cardboard is light, recyclable and easy to process. The cardboard can also be customized with different thicknesses and hardnesses as needed to meet the protection needs of different products.

[0021] Furthermore, the release box finished product 9 has a release box extension portion 6 extending upward on a specific side thereof.

[0022] Furthermore, the release box extension part 6 has a circular or elliptical hole in the center, the size of the hole is based on the diameter of the branch or petiole of the released crop, and there is a dotted line slanting downward between one side of the hole and the edge of the extension part for hanging on the host plant. This design allows the release box to maintain a certain distance from the plant, reducing potential damage to the plant, while ensuring that the ladybug pupae can be successfully transferred to the plant at the appropriate time.

[0023] Furthermore, the release box product 9 has semicircular holes on the side near the bottom, with a hole diameter of 2.5-3mm and a chord center distance of less than 0.5mm. This hole diameter can ensure that the pupae of the multi-heteromorph ladybird cannot pass through, but the emerged adults can pass through.

[0024] Furthermore, a supporting method is provided, which is to collect and package the pupae after they have been lured according to the characteristics shown in the breeding process of the multi-coloured ladybird.

[0025] Furthermore, a characteristic of the multi-hyphenous ladybird is that when raising the multi-hyphenous ladybird in a breeding box, it is found that the multi-hyphenous ladybird will gather at the upper angle of the box side wall to pupate. By covering the corresponding part of the box body with padding paper, the multi-hyphenous ladybird will concentrate on the padding paper to pupate, and then be released into separate boxes.

[0026] A padding paper 2 is placed inside the release box finished product 9, one corner of the padding paper 2 is a cutting area 3, a multi-color ladybird pupa body 1 is placed on the padding paper 2, a folding position 4 is set inside the padding paper 2, and the padding paper 2 can be folded through the folding position 4 to form a preliminary processed product 5.

[0027] Furthermore, the packaging box is packaged by cutting the paper sheets densely covered with Coccinella polymorpha pupae into small pieces according to the capacity of a single release box, and folding the paper sheets appropriately to form a crescent or "L" shape to form primary protection for the pupae, and then putting them into the release box for packaging.

[0028] Furthermore, the transportation and release of the sub-packaging boxes, after the ladybug release box is packed, it is transported to the release point, and there is no need to open the box. The dotted line of the extended part of the release box finished product 9 is torn off and hung at the release position; after release, the multi-color ladybugs gradually emerge, and because of their slender adult body, they can smoothly pass through the semicircular hole or the superior arcuate hole of the release box, and spread out to prevent and control field pests.

[0029] Embodiment 2

[0030] The packaging steps of a device for releasing Coccinella polymorpha pupae are as follows:

[0031] Step 1: Complete the first step of assembling the release box manually or by a packaging machine, fold the box into a column, and glue it into a four-sided prism without a top or bottom;

[0032] Step 2: Fold the "concave" part of the bottom of the release box into the first layer, then cover the two "L"-shaped parts on the "concave" part, then cover the "convex" part, press the protruding part into the intersection position, and complete the bottom assembly;

[0033] Step 3: Place the collected pad paper 2 with the plurality of Coccinella polymorpha pupae bodies 1 into the finished release box 9 from the upper opening of the release box, and seal the box to complete the packaging of the single finished release box 9;

[0034] Step 4: The packaged ladybug release boxes are placed in perforated cartons and stored in cold storage, or transported to the release point for release;

[0035] Step 5: When releasing, take out the release box, tear open the dotted line at the circular hole of the extended part of the release box finished product 9, and hang it along the opening direction to the petiole of the branch or large leaf of the release plant to complete the release;

[0036] Step 6: There is no need to open the release box during storage, transportation and release. The emerged adults will drill out from the semicircular holes or arcuate holes on the side of the release box and spread to the field for pest control.

[0037] Through the above steps, we can know that the whole assembly process is simple and clear, which can be completed quickly by manual or mechanical means. The structure of the device is stable, and a special box bottom structure ("concave", "L" and "convex" parts) is designed to ensure that the bottom of the release box is stable and can bear the weight of the pupae inside; it is easy to place and remove: the pupae of Coccinella multicolor are placed through the upper opening, which facilitates the loading process and can be easily taken out when not needed; suitable for storage and transportation: they are placed in a perforated carton, which ensures ventilation and facilitates batch processing, and cold storage prolongs the survival period of the pupae.

[0038] The utility model is aimed at Coccinella heterochromis multicolor, and designs a tool for releasing Coccinella heterochromis multicolor pupae due to its unique pupation position selectivity and aggregation of pupation positions during its breeding process, and improves the supporting use method. The utility model mainly provides a release container and a release method for Coccinella heterochromis multicolor pupae, and improves technical support for more complete natural enemy prevention and control work.

[0039] In summary, the release device for the pupae of the multi-color ladybird can make the release box finished product 9 simple in structure design, convenient for collection and packaging, and conducive to mechanization. At the same time, it is easy to release, the material is degradable, and no subsequent recycling is required.
